i `iiiApplicationjriidrendi-i,mit E 'Toall .whom it may "concern: Be it known thatl, ALBERT.`

York, have invented certain newand useful Improvements in Apparatus for Molding and Perforating Plastic Substances, of which the following isa specification.r .f K- 4. z My apparatus maybe used for molding ,va`= rions plastic substances finto self-sustaining ro blocks, and for perforating saidblocksyso-as to increase the amount of exposed-surface. .1Q My invention Aconsists ina novel construc- `tion of charging-frame for use in connection.

with vmy apparatus in` molding plastic subvstances into perforated blocks, and of Vsuch construction that the blocks'maybereadily removed therefrom when sufficiently hardened,

i protrude through one of the series of holes in` said table; i g

i It also consists in the combination, with such revolving table having guides upon its upper surface for holding vra ,number of charging- 3o frames arm extending from aV centralstandard and capable of being adjusted horizontally over a frame, or turned upwhen saidframe'is to `be removed. r i r It also consists in the combinatiomwith such revolving table and-vertically-movable plate,

of a novelarran gement of levers for elevating said plate. Y In theaccompanying drawings, Figure l 4o represents` a perspective view of a chargingpan for substances to be treatedwhich are or' such a nature that they will `not set quickly, so as toretain their form. Fig. 2 isa perspective view of a charging board an d frame for substances whichwill become solid or sety quickly, part of the said frame being broken away. Fig. 3 isa perspective view of an apparatus for perforating the lsubstanceto be treated while inthe molding pan or frame; 5o and Fig. 4 is a partial vertical section of the same.

Similar letters-ofreference designate corresponding parts in all` the figures.

.Thec'harging-pan A (represented in Fig. l) is intended for use with materials which do not 5 5 immediately become solid or set, but remain ina plasticzcondition for some time. The sides ofthis charging-pan are made daring from the bottom upward, so` that when i'nallyset the contents; of the panlmay beremoved in the 6o shape. ofgyfafbloclby turning. the pan upside down.,The bottom of the pan is perforated and isprovided with cleats c.

lFor molding substances-which quickly be. come solid or set into blocks I use the mold- 6 5 `ing-board B and frame C, (represented in Fig.

2.) Therrame G has itssides-flaring from the top downward, so that when the substance has setthe frame maybe readily lifted off, leavingthe, substance in the form of a block 7o on the, molding-board B. This molding-board is perforated like the bottom ofthe moldingpanA", andhas upon its under side cleats a, `like those upon the pan A. Y

`The"substance, after "being placed in the Amolding-pany or molding-frame, may be perforateth'fas shownin Fig. l, at b, `and I form as many perforations as can be made without breaking the massfso as to expose as large an amountof surface' as possible. Y

I `haye represented inV Figs. 3 and t an appa- -ratus which may-be conveniently used for perforating the contents ofthe pau A or frame G. D designates a table `adapted to revolve upon al central standard, c, and Vresting at its 8 5 outer Aedge upon rollers d, to enable it to be more easily revolved. It is provided with sev- .eral series (here represented as three in number) of holes, e, corresponding in number to the p'erforations to be made in the contents of 9o the pan or frame, and also with blocks f, serving to hold'the pans or frames in proper position on the table, as shown in Fig. 3. y E designates a plate or frame vertically movfable in stationary guides g, and provided with 9 5 agnumberofl upwardly-extending pins, h, corresponding in numberandposition with one seriesof holes, e, in `the table DI By meansl fof alever, F, the plate E may be raised into theposition shown in Fig.4, so that its pins 1o willv be projected partially or wholly through the contents of the Vpan or frame on the table from the side of the table'ou which is the per-` foratin g apparat-us.

H designates a hopper hinged to-an arnnJr,

extending' from the standard c, and which may be adjusted into the position shown in dotted outline in Fig. 3, over the molding-frame C, when the latter is to be filled or turned up, when the frame is to be replaced by another.

In operating my aplmratus, the pan or frame having' beenvplacedon the table D, the latter is revolved so as to bring' the pan oriframe over the plate or frame E and pins h. The hopper H is then adjusted'over the frame C, and the latter filled with the'substance to be molded in a plastic state. The plate E and pins h are thenv raised by the lever Gr, and when depressed the substance is left filled with pertorations. If the nature ot' thesubstance is suchthat it becomessolid quickly the frame C may be at once removed, leaving a perforated block, O, (represented in Fig. 3.) 1t' the nature of the substance is such: that it remains plastic for some time, pans like that represented in Fig. l are used.

By my invention I provide' a simple and easily operated apparatus whereby various kinds of substances may be molded into perforated blocks.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the charging-frame C, of the perforated charging-board B, substantially as and for the purpose specified.

2. The combination, with a revolving table pierced with two or more series ot' holes, of' a vertically-movable plate or frame provided with pins, stationary guides to limit said plate `to a vertical movement, and mechanism for raising said plate, whereby the said pins are caused' to protrude through aseries of holesin the said table, substantially as specified.

3. The combination, with a table' having guidesupon its upper surface for llolding a number of frames in position, of a hopper hinged to an armextendingA from ay central standard and capable'ot" being adjusted honi zontally over a frame orturnedl upawhen` said frame is to be removed, substantially as speci fied. l 4. Thecombinaton, with the revolving. ta'

Able'D, of the plate or frame E,-providedzwitll pins L,. the levers F Gr, and cord t', substantially as and. for the purpose-specified.y
